LIFX: The LED Light Bulb Reinvented

LIFX is a WiFi enabled, multi-color light emitting diode, energy efficient LED light bulb that you control with your iPhone or Android.

This sounded great. Energy efficient, LED bulbs which could change colour to match/create moods, and which you could control from your Smartphone? Where do I sign up? Well, I signed up on the Kickstarter page, obviously.
